Ultra-compact waveguide bandpass filters will be key elements in future satellite telecommunication systems. In spite of the excellent performance in terms of loss and power handling, size and mass are well known drawbacks of waveguide-based filters. Therefore, many efforts have been devoted to reduce the size of waveguide filters.Our research goal is to reduce the mass and size of such filters by the adoption of a TM dual-mode cavity loaded with a high-permittivity cylinder.

High Frequency Electronics (HFE) Lab, was founded in 2001 by inheriting ten years of experience in the area of modeling and design of microwave electronic circuits. This experience has been further exploited and finalized to several technological and scientifc challenges. Among them it is worth mentioning those running at present:
